HORIITIO BLAKE BECKMAN, OF NEWBURGH, NEW YORK.

SHUTTLE-BINDER.

SPECIFICATION forming part of Letters Patent No. 779,344, dated January 3, 1905. Application filed May 28, 1904. Serial No. 210,171.

To aZZ whom it may concern:

Be it known that I, HORATIO BLAKE Bnox- MAN, a citizen of the United States, and a resident of Newburgh, in the county of Orange and State of New York, have invented a new and Improved Shuttle-Binder, of which the following is a full, clear, and exact description.

My invention relates to a shuttle-binder for looms.

Heretofore shuttle-binders have been made of a solid block of wood or metal and provided with a curved operating-surface for causing the shuttle to bind as it enters the shuttle-box, and therefore for its motion to be retarded sufiiciently to prevent injury to the pickerstick. In the old-style shuttle-binders it is well known that the power used in swinging them upon their pivots from their forward position to their retracted position is considerable, and on account of their weight it has a great deal to do with the waste of power in looms and greatly increases the jar on the machinery and the noise produced by its operation. My improved shuttle-binder is designed to overcome all of these defects. I have discovered that by making the shuttlebinder in such a manner that a part of the operating-surface is capable of yielding and another part rigid I can produce a device which is much lighter than the metal binders heretofore used and is also much more durable than the wooden ones. This result I preferably accomplish by making the shuttlebinder in the form of a sort of skeleton frame consisting of two parts, one of which is straight and the other of which is curved and longer than the other.

Other objects and advantages will appear in the course of the subjoined description, and the novel features which I regard as my invention or discovery will be particularly pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the figures.

Figure 1 is a front elevation, partly in section, on the line 1 l of Fig. 2, showing certain parts of the loom and the position which my improved shuttle-binder occupies with respect to those parts. Fig. 2 is a sectional view of the same on the line 2 2 of Fig. 1. Fig. 3 is a plan view, partly in section and on an enlarged scale, of a preferred form of my shuttle-binder; and Fig. 4 is a sectional view on the line a 4 of Fig. 3.

In the drawings the shuttle-binder is shown as consisting principally of two parts a and 6. The part a is longer than the part I) and is provided with a convex curve a, at the highest point of which it is the farthest distance from the part b. It also has a concave curve a between the curve a and one end of the shuttle-binder. These terms concaveand convex as used apply to the outside of the device-that is, the side shown at the bottom of Fig. 3. The part 7), which constitutes a tiebar, is perfectly straight and is secured at its ends to the part a by means of rivets c and c. The rivet c is provided with a tapering head 0 or it may be made tapering throughout its length in order to hold a plate (Z, which is applied to the back of the binder for the purpose of receiving the blow from the binderfinger or other device which is used to force the binder inwardly into the shuttle-box in position to be struck by the shuttle.

The shuttle-binder is provided with an eye 0, by means of which it is pivoted at f to the body of the loom in, a well-known manner. The manner in which the binder is operated on its pivot is well-known and does not need description any further than to say that any known means may be employed.

The various parts of the shuttle-binder are preferably made of metal, and aluminium is the metal which I prefer to use, although my invention is not limited thereto, and I retain the right to use any desired or convenient metal or other material. I

In the construction of the device as represented in the drawings and above described it will be obvious that when the shuttle is driven into the box it will first strike the binder at some point in the concave curve (0 which will yield slightly, and thereby prevent part of the shock and noise, which is a feature of all shuttle-binders heretofore known. As the shuttle passes onward in the box it will be consequently subjected to greater pressure by the bar (0 until, when it reachesthe convex curve a, which is perfectly rigid on account of the tight bar I), the effect will be the same as that produced by the highest points in the curves of the solid shuttle-binders now in use. Consequently the shuttle will be first gently retarded and finally stopped by the two curves on the piece of metal a.

The reason for the rigidity of the curve a will be obvious. The bar 6 being securely fastened at its ends to the ends of the bar a will not yield in any manner, and the only Way in which elasticity could be given to the convex curve a wouldbe the yielding of this bar I). On the other hand, the concave curve a can yield, for the reason that it does not need to force the ends of the bar 6 apart, but can be pressed downwardly toward the bar 6 on account of the particular shape of the curve between the end of the binder and the curve a.

The plate (Z is subjected to a great deal of wear in devices of this character, and as its surface wears away it would become loosened if the rivet 0 were merely provided with two rivet-heads in the same manner as the rivet a is constructed; but with the construction of the rivet 0, in which it gradually tape-rs outward toward the outer end of the plate, it will be obvious that any wear upon the outer surface thereof will leave this rivet with a head at 0 which will securely hold the plate in position on the shuttle-binder.

\Vhile I have illustrated and described a particular embodiment of my invention, it will be obvious that many modifications may be made therein and that the invention is not limited thereto.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. A shuttle-binder formed of two pieces of aluminium fastened together at their ends,one of said pieces having a yielding portion and an adjacent rigid portion intermediate of its ends.

2. A shuttle-binder formed of two pieces of metal fastened together at their ends, one of said pieces being longer than the other and. having a yielding portion and a rigid portion- 3. A shuttle-binder formed of two pieces of metal of unequal lengths, one of said pieces being flexible and having a rigid portion intermediate of its ends.

4. A shuttle-binder for looms comprising a piece of spring metal, having on its operative face a yielding portion and a rigid portion.

5. A shuttle-binder having on its operative face a concave yielding portion and a convex rigid portion.

6. A shuttle-binder for looms, having on its face near the end at which the shuttle is designed to strike it, a concave yielding portion, and having at the rear thereof on the same face a convex rigid portion.

7. A shuttle-binder formed of two pieces of metal of unequal lengths fastened together at their ends, the longer of said pieces being flexible and having a concave yielding portion and a convex rigid portion.

8. A shuttle-binder for looms, formed of two pieces of metal and having a plate, and a tapered rivet passing through said plate and, binder for securing said parts together,

In testimony whereof I have signed my name to this specification in the presence f t b scribing witnesses.
